A tag is used to label and mark a specific commit in the history.It is usually used to mark release points (eg. v1.0, etc.).Although a tag may appear similar to branch, a tag, however, does not change.It points directly to a specific commit in the history.

If you're using IntelliJ... If this is your first time using IDEGen... Android is large, thus IDEA needs a lot of memory. Add "-Xms1g -Xmx5g" to your VM options in "Help > Edit Custom VM" and increase the file size limit in "Help -> Edit custom properties" by adding "idea.max.intellisense.filesize=100000". Make sure to restart the IDE for the new settings to take effect. Create a JDK configuration named "1.8 (No Libraries)" by adding a new JDK like you normally would and then removing all of the jar entries under the "Classpath" tab. This will ensure that you only get access to Android's core libraries and not those from your desktop VM. From the project's root directory... Repeat these steps after each sync... 1) make (to produce generated .java source) 2) development/tools/idegen/idegen.sh 3) Open android.ipr in IntelliJ. If you already have the project open, hit the sync button in IntelliJ, and it will automatically detect the updated configuration. If you get unexpected compilation errors from IntelliJ, try running "Build -> Rebuild Project". Sometimes IntelliJ gets confused after the project changes significantly.
